Yeah, I think we should just get rid of those bits. I don't remember
seeing *any* complaint when INT64_IS_BUSTED was removed, which means
nobody was using that code anyway.

Now there is one more problem in this area which is that the patch
defined a new type pg_int64 for frontend code (postgres_ext.h). This
seems a bad idea to me. We already have int64 defined in c.h. Should
we expose int64 to postgres_ext.h somehow? Should we use standard-
mandated int64_t instead? One way would be to have a new configure
check for int64_t, and if that type doesn't exist, then just don't
provide the 64 bit functionality to frontend.
